Abstract
Introduction. Insect-plant interactions are affected directly or indirectly by stress factors. The effect of environmental resource availability on insect-plant interactions is here reviewed. Subsequently, the analysis focuses on aphid-host plant interactions, particularly in the system composed by the green peach aphid Myzus persicae and its primary host plant Prunus persica. Literature. Plant defenses arise in two ways: resistance and tolerance, both are affected by abiotic factors. The information gathered from studies (n = 29) on plant-aphid interactions addressing the reduction in water availability on plant resistance, showed that in 41,4% of the studies, drought stress elicits lower resistance, while 34.5%, 20.1% and 3.4%, showed higher, no change and conditional effects on plant resistance, respectively. Conclusions. Water stress elicits mixed effects on plant resistance to aphids. However, the literature review also suggests that cultural practices play a role in the fate of the peach-aphid interactions, whereas the development of predictive models aimed to assist crop-pest management systems still requires more basic information. Aphid responses to plant defenses under stressed conditions are still largely unexplored.
Highlights
Insect-plant interactions are affected directly or indirectly by stress factors
The co-adaptation, co-evolution and co-speciation between herbivores and their host plants have been a central topic of modern biology in recent decades
We focus on two of these processes: plant response to insects and abiotic environmental factors mediating these responses, focusing on aphidplant interactions
Summary
Insect-plant interactions are affected directly or indirectly by stress factors. The effect of environmental resource availability on insect-plant interactions is here reviewed. Myzus persicae, defense mechanisms, host pathogen relations, resistance to injurious factors, resources. La complexité des interactions insectes-plantes en fonction de différents niveaux de ressources et de résistance de l’hôte : le cas de Myzus persicae-Prunus persica (synthèse bibliographique) Introduction. L’effet de la disponibilité des ressources sur ces interactions est en premier lieu abordé au sens large, suivi d’une analyse ciblée des relations impliquant le modèle puceron, en particulier le puceron vert du pêcher Myzus persicae et son hôte principal, Prunus persica. Les informations recueillies à partir d’études (n = 29) concernant l’effet de la diminution de la disponibilité en eau sur les défenses contre les insectes, ont montré que dans 41,4 % des études, le stress hydrique induit la résistance.
